OT: Jboss 4 + Tomcat 5.5.26 integration

[soup_or_power]

Sorry for posting here. Couldn't get any help from Jboss forums.

Basically trying to integrate Tomcat5.5.26 with Jboss 4. The steps
taken are as follows:
a) download Tomcat 5.5.26 and unzip into a folder
b) copy all the jar files from Tomcat5.5.26 to $JBOSS_HOME/server/all/
jbossweb-tomcat55.sar
c) start jboss

The problem is: jboss won't deploy the war files. The typical error
message is:


ObjectName: jboss.web.deployment:war=web-console.war,id=335930099
State: FAILED
Reason: java.lang.NoSuchMethodError:
org.jboss.web.tomcat.security.JaccContext

I am wondering if I need tomcat6-service.jar instead of the current
tomcat55-service.jar.

I'd appreciate any help you can offer me.

Thanks
